[android-developers] Displaying Text anywhere on the screen Dynamically
Hi, I'd like to display text on the screen on top of a drawable anytime there is a OnTouch trigger (which is handled). Is it possible? I found TextView and TextPaint but neither of these texts will display itself anywhere in a chaotic fashion, and it won't display itself on top of a drawable. see link for an image of what I want. http://ups.imagup.com/07/1264601491.png The goal would be to be able to select these object (which graphically would be represented by the text and the drawable) and do stuff with it. Ideally I want to do : Text t=new Text(hello , x , y); Thanks for any information you can provide -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Audio in the emulator...
The problem is now resolved, I had make several mistakes:
I had forgot to release the recorded sound. (record.release();)
I hadn't put the complete path for the sdcard which in fact prevented
the emulator from loading one.
audio-in is useless with windows, plug and play does the job.
I didn't play the sound from the path I had recorded it in.
The sdcard must be a *.img file and not a *.iso (*.iso doesn't work
for me)
thanks

Sorry, I don't have a Windows machine for testing. Maybe one of our
developer advocates can help you with that.
From the debug spew from the audio input driver, it sounds like it
should be recording. Do you see the file being written to the SD card?

Try this:
emulator -help-audio-in
It will tell you which audio backends are available on your system.
You didn't specify what OS you are using.
I think there was also some sample code in the SDK at one point. Maybe
one of the developer advocates can point you to it. Another option is
to look for the source for the Sound Recorder application on
source.android.com. It should be in packages/apps/SoundRecorder.

Hello,
I have been searching for some time and I can't find a detailled
tutorial on how to easily record and then read audio on the emulator
under eclipse. I have found these steps:
- You have to install a virtual sd card with mksdcard.exe 1024M
sdimg.iso
-then run the emulator : emulator.exe -sdcard
sdimg.iso //where sdimg.iso it is the path to
the sdcard
-then run adb.exe : adb push local_file sdcard/remote_file
-then you should put : uses-permission
android:name=android.permission.RECORD_AUDIO/uses-permission in
the androidmanifest.xml
-then there is some code to implement which should look like :
private void startRecord() {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
//ok
so
I say audio source is the microphone, is it windows/linux microphone
on the emulator?
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(/sdcard/test.3gpp);
recorder.prepare();
recorder.start();
}
-then you should stop with : recorder.stop(); // at some point (I have
no idea when and where to decide to stop but I haven't searched yet)
-then you should play it.
I have also heard about :
http://code.google.com/intl/fr/android/reference/emulator.html#sdcard
in this page of the manual (~1/4 of the total scroll), there are some
informations about Emulator Startup Options, one of them is about
Media -audio backend
I couldn't find much about that backend thing, google didn't said much
about it. I still don't know if it's important to the audio recording
process.
The fact is all these steps are pretty blurry to me, and I believe I
am not the only android newbie trying to record some sound :)
Anyone knows where we can find a complete tutorial for dummies
teaching this feature?
Any help is of course greatly appreciated
Thanks.

[android-developers] Re: MediaRecorder - No value other than 0 returned from getMaxAmplitude
are you testing it on the emulator or on the G1 device? I'm not sure about it but I've read around some forums that you need a virtual sd card to record audio on the emulator. (with the mksdcard.exe in the tools provided with the sdk) Some other sources also say it isn't possible to record audio on the emulator yet. Check if you can read/hear what you have recorded since you are using a sdcard, maybe the sdcard is too small. Why would you use a thread to return the max amplitude? I am myself looking forward to record audio on the emulator and constantly find contradictory informations about whether it's possible or not. the manual says it's not. Any insight about that is appreciated in addition to the upper problem. thanks On 31 jan, 15:12, ph...@grantmidwinter.com ph...@grantmidwinter.com wrote: I've got a media recorder, prepared and started in the following way: mRecorder = new MediaRecorder(); mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mRecorder.setOutputFormat (MediaRecorder.OutputFormat.THREE_GPP); mRecorder.setAudioEncoder (MediaRecorder.AudioEncoder.AMR_NB); mRecorder.setOutputFile(/sdcard/test.3gpp); mRecorder.prepare(); mRecorder.start(); I'm then using a thread to return the mRecorder.getMaxAmplitude int, but it never returns as anything but 0. I've looked all over for why this might be happening - but I'm at a complete loss now so help would really be appreciated.
